Question

您好我正在尝试使用kotlin和spring boot构建一个应用程序，同时在docker上运行postgres图像，但我一直收到此错误

@Entity
data class User(
    @Id
    @GeneratedValue
    val id: Long,
    val firstName: String,
    val lastName: String,
    val age:Int,
    val gender:String
    )

.....

这是我的实体

import org.springframework.data.jpa.repository.JpaRepository
import org.springframework.stereotype.Repository

@Repository
interface UserRepository : JpaRepository<User, Long>

这是我的资料库

@RestController
class UserRestController {


    @Autowired
    lateinit var userRepository: UserRepository

    @RequestMapping(value = "/addUser")
    fun save(): User {

        return userRepository.save(User(id=1,firstName = "chaima",lastName = "ennar",age = 20,gender = "female"))

    }


}

这是我的控制器

server.port=${PORT:9000}
spring.cache.cache-names=googleFeeds,internationalFeeds
spring.cache.caffeine.spec=maximumSize=100,expireAfterAccess=1800s
spring.datasource.url=jdbc:postgresql://localhost:5433/irooldb
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.hibernate.ddl-auto=update
spring.jpa.generate-ddl=true

这些是我的属性

        <script>
            //Extract
            console.log(MyJSON[1].url)
            var cajas = 2
            var boxsaved = MyJSON.length
            fnc = function(info) {
                hey = document.getElementById("hl1").innerHTML = info.url;
            }
            //box creator
            sm = function agregar_caja() {
                document.getElementById("inf").innerHTML += "<p type=text id='hl" + new String(cajas + 1) + "'><br>"
                cajas = cajas + 1
            }
            //Loops
            for (i = 0; i < boxsaved; i++) {
                sm(MyJSON[i]);
            }
            for (i = 0; i < MyJSON.length; i++) {
                fnc(MyJSON[i]);
            }
        </script>
</body>

我的问题是：这个错误意味着什么？我做错了什么？

Answer 1

这似乎与此问题重复：java.lang.NoSuchMethodError: javax.persistence.spi.PersistenceUnitInfo.getValidationMode()Ljavax/persistence/ValidationMode;

您似乎从运行时类路径中选择了JPA v1 libraty，但是您尝试调用的方法是在JPA v2中定义的
